With the introduction of combinatorial chemistry and high throughput screening, the properties of new chemical entities shifted towards higher molecular weight and increasing lipophilicity that results in decreasing aqueous solubility. It is not surprising that many drug candidates have poor water solubility since the initial selection of drug candidates are based on activity alone. Other physiochemical and biopharmaceutical properties such as permeability, biopharmaceutics and metabolism are rarely considered during the selection process. The aim of this study was to increase dissolution rate of felodipine poorly soluble drugs from BCS class II by complexation process. Complexation was prepared using β cyclodextrine. Different techniques were employed for preparation of complexation with β cyclodextrin like physical mixture, cogrinding, kneading technology, solvent coevaporation.The physical properties of the prepared solid mass of felodipine was characterized by in vitro dissolution studies, UV- spectroscopy, Fourior transform infrared spectroscopy, differential scanning calorimetry (DSC) and  X-ray powder differaction spectroscopy. Additionaly, phase solubility studies were performed to support the in vitro dissolution study. The results of Fourior transform infrared spectroscopy shows the compatibility of drug with cyclodextrin, while differential scanning calorimetry (DSC) and X-ray powder differaction spectroscopy showed the confirmation of complexation of β cyclodextrin with felodipine.

Tissue culture
(often called micropropagation) is a special type of asexual propagation where a very small piece of tissue (shoot apex, leaf section, or even an individual cell) is excised (cut-out) and placed in sterile (aseptic) culture in a test tube, petri-dish or tissue culture container containing a special culture medium.Several industries and nurseries have standardized protocols for the multiplication of ornamentals like orchids genera, carnation, roses, chrysanthemum and plantation crop like banana and cardamom..The compounds responsible for the memory enhancing effects of Bacopa monniera are triterpenoid saponins called bacosides .In the Ayurvedic Materia Medica, Bacopa has been recognized for its brain enhancement characteristics. Bacopa monnieri, a member of the Scrophulariaceae family, is a small, creeping herb with numerous branches, small oblong leaves and light purple flowers. In India and the tropics it grows naturally in wet soil, shallow water and marches. Brahmi (Bacopa monnieri) (Linn) familyScrophulariaceaeis also known as Madhyarasayana in Ayurveda as it increase mental-clarityand brain stimulating action It also possesses anti-inflammatory, analgesic, antipyretic, epilepsy, insanity, anticancer and antioxidant activities, saponins such as bacosides A, B, C and D which are the active triterpenoid principles and known as "memory chemicals".Only  a  very limited research has been  carried  out  on the plant,  under  the present study  assumes singular  significance and it is supposed to contribute a great deal to the existing literature. The present paper highlights the morphogenic response of various auxins and cytokinins on Bacopa monniera.

The essence of essential medicines underlies in satisfying the priority health care needs of the population. The selection of essential medicines is one of the core principles of a national medicine policy as it helps to set primacies for all the aspects of the pharmaceutical system and helps in the maintenance of a proficient healthcare system globally. Devising of essential medicines and national medicine policy is fast emerging as global concept of high relevance to the public irrespective of their nationalities. The prevalence of dreaded diseases like HIV, cancer, and a worldwide upsurge in case of malaria, tuberculosis and other infectious diseases with an addendum problem of multidrug resistance has further augmented the relevance of essential medicines and formulation of a rigid comprehensive national drug policy under the endorsement of WHO medicine strategy andimplementing the same under a complete implementation plan or master plan. This review emphasis the development and selection of essential medicines along with Indian scenario. This review also emphasis the mission, objectives, components, devising and implementation of essential medicine policy along with WHO tenets and regulations.

Pantoprazole sodium is proton pump inhibitor and used as an antiulcer agent.  The study was undertaken with an aim to formulate pantoprazole sodium enteric coated pellets.
Before going to develop the formulation a detail product literature review was carried out to know about the MUPS and type of dosage form available in market. The present study was focused to formulate delayed release capsule by MUPS Technique.
Average pellets size was determined by sieve analysis and found to be 1680-1200 microns (ASTM sieve no. 12-16). Sieve analysis was the essential step before coating. Because uniform sized pellets undergo effective coating. The result indicates a effective enteric coating and delay the drug release, with 32% acryl ezee solution, is possible. The formulation developed can further be worked on. For identifying a best formulation for delayed release pellets of pantoprazole sodium.

defines Good Manufacturing Practices (GMP) as “that part of quality assurance which ensures that products are consistently produced and controlled to the quality standards appropriate to their intended use and as required by the marketing authorization.” GMP covers all aspects of the manufacturing process:  validated critical manufacturing steps;  approved written procedures and instructions; records to show all steps of defined procedures have been taken. The guiding principle of GMP is that quality is built in to a product, and not just tested in to a product. Therefore, the assurance is that the product not only meets the final specifications, but that it has been made by the same procedures under the same conditions each and every time it is made. There are many ways this is controlled – validation is that part of GMP that ensures that facility systems, equipment, processes, and tests procedures are in control and therefore consistently produce quality product.

Abstract :
Carbodithioic acid esters of naphthylmethylamine prepared by replacing the amino function in amino methyl side chain with carbodithioic acid ester group and by adding various S-2-hydroxy propyl ester of dialkyl carbodithioic acid at amino group. Some of these compounds showed better spermicidal activity. The study revealed that incorporation of carbodithioic acid residue directly into naphthylmethylamine leads to compounds with better spermicidal activity and naphathalene-1-yl-methyl-carbodithioic acid-3-dialkyl amino-2-hydroxy-propyl ester has shown better profile than nonoxynol-9. Further, lead optimization may yield a potent spermicide.
